  1. More Data Center Tools Chad Trabant and Rick Benson IRIS DMC Data Management Workshop São Paulo, Brazil

  2. SHAPE SoftwareSEED Header Assembly and Preparation Engine SHAPE - Build dataless SEED files from SEED RESP and other info Controlled with a Header Assembly Template (HAT) file in XML format wherein SHAPE finds the needed details for building a SEED file including names of RESP files and blockette field values • Easily used in scripts, good for batch creation of dataless SEED, complimentary to PDCC at this point • Good for templating (common components defined once) • Java, runs anywhere a JVM is available Available from http://www.isti.com/~sid/shape/ Data Management Workshop São Paulo, Brazil

  3. SHAPE HAT Examples SHAPE Header Assembly Template examples Field substitution: Very simple example: Data Management Workshop São Paulo, Brazil

  4. Portable SEED File Reading Jrdseed - Java port of the IRIS-DMC’s ‘rdseed’ • Reads full SEED, dataless SEED and Mini-SEED+dataless • Writes SEED, SAC, AH, CSS, SEED RESP • Time-window and other output selection possible • Runs anywhere a JVM is available • Based on generic JavaSeed classes available separately Data Management Workshop São Paulo, Brazil

  5. libmseed - Mini-SEED Library • Allows reading and writing of Mini-SEED records. • Written in C. • Supports all structures of SEED 2.4 with a few minor caveats (blockette 2000 and blockette 405). • Supports all valid record lengths. • Supports ASCII, int-16, int-32, float-32, float-64, Steim-1 and Steim-2 encoding formats. • Tested on Solaris, Linux, Mac OSX and MS-Windows. • Supports big or little endian data records, all data read on a given machine will be in the local byte order. • Manages arbitrarily long continuous trace segments and groups of continuous trace segments composed, for example, of many Mini-SEED records. Writing of traces or trace groups to Mini-SEED. • Design to be used in multiple ways from very detailed oriented handling to hiding all the details of the SEED data format. • Able to read full SEED volumes by skipping the non data records. Available from: http://www.iris.edu/pub/programs/ Data Management Workshop São Paulo, Brazil

  6. Example libmseed programs msi - Mini-SEED Inspector Parse and print useful information about Mini-SEED in one or many files. Including continuous segment construction, data sample printing, etc. msstat - Calculate minimum, maximum, arithmetic mean, standard deviation and RMS for Mini-SEED in one or many files. msrouter - Sort Mini-SEED records based on one or many format details (network, station, location, start time, sample rate, quality, etc.) PQLII/PQLX - Data visualization/analysis program using libmseed. Data Management Workshop São Paulo, Brazil

  7. Example converters seisan2mseed - SeisAn to Mini-SEED converter mars2mseed - MARS 88/lite to Mini-SEED converter gse2mseed - GSE 2.0/2.1 or IMS 1.0 to Mini-SEED converter, supports both INT and CM6 data encoding sac2mseed - SAC to Mini-SEED converter mseed2sac - Mini-SEED converter to SAC converter All run on Linux, Solaris, Mac OSX and MS-Windows Available from: http://www.iris.edu/pub/programs/converters/ * Many other converters are available at the IRIS-DMC, IRIS-PASSCAL, ORFEUS, etc. Data Management Workshop São Paulo, Brazil

  8. PQLII/PQLX/PQLY Software The evolution of the PASSCAL Quick Look software for data viewing and analysis Key new features: • - Data display organized as continuous time series (by channel), large data sets • - Read event hypocenter information and phase picks • - Sorting by distance from user-specified location or known event • - Compute and display predicted arrivals based on hypocenter event info • - User-defined filters • - Trace alignment based on picks • - Compute cross-correlation coefficient between selected traces • - Integrate and differentiate time series • - Read "RESP" format metadata • - Remove mean from trace • - PSD and PDF plots • - Remove instrument response PQLII available from: http://www.passcal.nmt.edu/software/software.html Data Management Workshop São Paulo, Brazil

  9. Real-time Data Exchange A number of open-source and commercial data exchange systems exist, the bridges between them are illustrated below. Data Management Workshop São Paulo, Brazil

  10. Content • SHAPE - Build dataless from RESP - Easily used in scripts, good for batch creation of dataless, complimentary to PDCC at this point. - Good for templating with common SEED. - Java, runs anywhere. • Libmseed overview - more than simple record reading • Libmseed based tools: msi, msrouter, msstat • Libmseed based converters: seisan2mseed, gse2mseed, sac2mseed, mseed2sac, mars2mseed • Mention a number of internal DMC data fixing tools are available upon request, some similar to what PASSCAL uses. • PQLII/PQLX/ILL • Jrdseed • Real-time systems and bridges… • Verseed usage? (need more?, already illustrated in QC portion) • JPlotResp/JEvalResp (maybe done at end of PDCC lab?) Data Management Workshop São Paulo, Brazil
